Polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) were measured in indoor dust of three microenvironments in Durban, South Africa. The sum of eight PBDEs and three PCBs were quantified by gas chromatography with mass spectral detection. The mean concentrations of ∑n = 8 PBDEs and ∑n = 3 PCBs in 10 homes, 11 offices, and 13 university students' computer laboratories were 1710, 1520, and 818 ng/g, and 891, 923, and 1880 ng/g for PBDEs and PCBs, respectively. The concentration of PCBs found in homes was independent (P = 0.0625) of building construction year. Similarly, no relationship was observed between PCB concentrations and floor type. The concentrations of PBDEs correlated (r = 0.60) with PCB concentrations in homes, thus assuming similar sources. The elevated concentrations of PBDEs and PCBs may have significant implications for human exposure.
在南非德班的三种微环境的室内灰尘中对多溴二苯醚（PBDEs）和多氯联苯（PCBs）进行了测量。采用气相色谱 - 质谱检测法定量了8种多溴二苯醚和3种多氯联苯的总量。在10个家庭、11间办公室和13个大学生计算机实验室中，∑n = 8多溴二苯醚和∑n = 3多氯联苯的平均浓度分别为1710、1520和818 ng/g，以及891、923和1880 ng/g（多溴二苯醚和多氯联苯）。家庭中发现的多氯联苯浓度与建筑建造年份无关（P = 0.0625）。同样，未观察到多氯联苯浓度与楼层类型之间的关系。家庭中多溴二苯醚浓度与多氯联苯浓度相关（r = 0.60），因此假定来源相似。多溴二苯醚和多氯联苯的高浓度可能对人体暴露有重大影响。
